متن کاملImproving Utilization of the Atlantic Sea Scallop Resource: an Analysis of Rotational Management of Fishing Grounds
An age-structured bioeconomic model was constructed to determine optimal patterns of exploitation for the U.S. Atlantic sea scallop fishery. Results indicated that economic rents are maximized by engaging in pulse fishing strategies, whereby fishing only occurs following a multi-year closure period. Closures allow biomass to accumulate undisturbed for several years in a row, leading to the harv...
